Apparatus for controlling coasting operation in hybrid vehicle, system including the same, method thereof

A method of controlling a coasting operation in a hybrid vehicle, the method comprising:

• determining, by a coasting operation control mode entrance time point determination unit, a first time point at which a subject vehicle enters a coasting operation control mode;
• calculating, by a target vehicle speed reach time point calculation unit, a target vehicle speed of the subject vehicle and a second time point, at which the subject vehicle reaches the target vehicle speed, when the subject vehicle enters the coasting operation control mode;
• and
• controlling, by a clutch lock-up control unit, clutch lock-up using a present vehicle speed of the subject vehicle and a present vehicle speed of a front vehicle in the coasting operation control mode.
